Hi how can we increase or decrease the size of the circle. I mean from big circle to small, small to big in slow motion. Can any one help me please.

am very sorry philho for late reply,am out of town can u explain with some sample code.
my thesis project is visualizing emails. in my project am showing number of emails data in visual way  am getting problem in my
code

void drawData(float x, float y, String abbrev) {
float value = locationTable.getFloat(abbrev, 3);
float radius = 0;
if (value >= 0 && value<=55) {
//radius = map(value, 0, dataMax, 1, 10);
a+=0.05;
fill(#4422CC); // blue
} else {
 b+=0.05;
//radius = map(value, 0, dataMin, 1, 10);
fill(#FF4422); // red
}
ellipseMode(CENTER);
//pushMatrix();
//rotate(a);
ellipse(x, y, a%15, b%15);

where a and b are global variables in this code i want to show ellipse in animation way increase or decrease and ellipse size should be small if value is more eg: value = 54 ellipse should be small in animation way, if value is more than 60 ellipse size should be more.

Thank you very much for u help

regards

I fear I hadn't fully understood your needs (I get that English isn't your first language...).
In particular, I don't get the "in animation way" part.
Nor what are the start / end values, etc.
